Red oil pressure light flashing

Hey all,

Sorry for my english it's not my natural language, but this forum seems to be the best I ever seen about Skoda.

Red oil pressure light flashing in my Skoda Fabia SDI 2001.

So I checked oil level and it was under the low. I immediately complete to normal level. But red light continues flashing.

I have checked with oil pressure gauge. It gives me this values

~1000 rpm : 2.0 bars

@2000 rpm : 3.5 bars

@3000 rpm : 4.5 bars

There is no pressure variation while I maintening engine speed.

What do you think about this values ?

I replaced the sensor and it didn't fix it. Oil, filters, are new.

Red light starts to flash @2000 rpm.

I was having others electrical problems before that. The speed meter not working during some miles and when I decelerate engine jerking.

Any ideas ? Electrical problem ?

Best regards
